Specify Name of logfile: -l <logfile>

The default logfile name has the form of ./vnc_logs/date/time. You can explicitly specify the logfile of the jobs you submitted by this option, for example:
% nc run -l /home/john/logs/log1.log sleep 10
Warning: Conflicts may occur if same log file is used for multiple jobs. New users are not recommended to use this option.
